The cucumber cultivar‘Jingyan Mini 2’was used as the experimental material to study on Thrips tabaci Lindeman (Thysanoptera:Thripidae) and Aphis gossypii Glover(Homoptera:Aphididae) in solar greenhouse.The population dynamic and spatial distribution of two species were studied on cucumber from planting to harvest in a solar greenhouse in order to provide a basis for effective control of cucumber pests.The results showed that when average temperature was above 20 ℃,the population of T.tabaci and Ap.gossypii started to rise.T.tabaci tended to Logistic growth and Ap.gossypii tended to exponential growth.Both T.tabaci and Ap.gossypii followed negative binomial distribution pattern.The distribution of T.tabaci in solar greenhouse varied obviously over weeks.On contrary,the largest population of Ap.gossypii presented in west all the time.
